pensively manufactured swivel head 'hy- 1 I drant.

It'is a particular object of the present invention to provide a swivel head hydrant with as few parts as is possible with practical construction, and to provide a ozzle or head member capable of being turned v through a complete circle, and to provide a leverhaving the'dual functions of an operating means and a locking means to hold the hydrant head in any desired position with relation to the stand-pipe.

1 The'invention consists of the parts and 1 the construction and combination of parts as hereinafter more fully described and.

claimed, having reference to the accompa nying. drawings, in which Figure 1 is a side elevation of the hydrant. Fig. 2 is a central, vertical section through the hydrant in a plane at right angles to Fig. 1. a

In the drawings, 2 represents a stand-pipe connectible to a suitable source of supply and having secured at its upper endaan annularly flanged member 3, the diametral face 4 of which is adapted to form a seat; and centrally within the seat member 3 there is formed or provided ;a stationary bushing 5, internally threaded as at 6 :and forming anut. Mounted upon the hydrant seat 3 is a hydrant head7; here shown as of spherical form, with a radial nozzle or discharge mouth 8 at oneside, and having a flange or bearing face 9 to fit and turn upon the surface 4: of the valve seat 3. -Extending diametrically through the hydrant head 7 and projecting from the top thereof is a valve spindle 10 vhaving intermediate its ends a stop shoulder 11 and also a bearing shoulder '12, andagainst the latter there rests a disk plate 13 turnable on the stem, forming the closing member of the valve; and being prevented from longitudinal movement upon the. spindle 10 by a pin or other suitable stop 14. The lower end of 8 the disk plate 13 will, or moved toward the valve seat 41 to control nut 5 which is mounted against rotation as UNITED sTATEsr Tn 'r onrron.

the valve stem lt); is threaded as at 15 to {engage the complementary threads of the suitable handwheel or other device 16 :wherebythe stem may-be revolved and through its engagement with thjestationary to the direction of its turnin the discllalge'i therethrough. f The shoulder 11 of the valvestem 10 limits the upward nut 5 the stem 10 will rise or fall according e a gmovement, so a a e e lifted from movement of the valve and stem toprevent 3 v the';screw"15 frompassingentirely. out of e the nut 5. For the purpose ,of ,annularly turning the hydrant head 7 as to thestand- .p pe 2, the hydrant head 7 is provided with diametr cally opposite depending journal brackets 17 which overhang the circumference of the flange of the valve niember 3i and pivoted upon the journal brackets 17 of the hydrant head is a yoked lever 18, the

ends of the arms ofwhich are preferably a formed with eccentrichubs or cam surfaces i 19 whichwhenthe lever-"18 is swung downwardly act to bind upon the lower surface of the flange of the: valve seat member, 3,

the valve member 3.

formed on theflange 9 so as to embrace the I and temporarily butjsecurely lock the hy- A drant head 7 in an angular position-upon I i circumference of the flange of thernember 3, and thus prevent eccentric movement of the hydrant head 7 as to the seat member .The operation of the hydrant isasfollows: iWith the several parts assembled as headf7fso that; the nozzle '8 thereof "will shown the operatormay turn the hydrant a stand at the desired anglelas; to the standpipe 2 by grasping the operatinglever" 18 and tilting it aboutfitspivot. on zthe b-rackets e a 117 so as to disengage the locking surfaces, 19 from the flange of the part 3. After having turned the hydrant head 7 by swinging 8 -i it m a horizontal plane through means of the lever 18, the hydrant head may thenjbe I looked firmly in position by the downward movement of the lever 18 which will then press the eccentric or cam surfaces 19 into contact with the contiguous flange of the, j

- discharge of liquid or fluid through the named flange, V g v d 2, In combination vvith a stand pipe, a,

valve is controlled by turning the hand- Wheel 16 which turns the valve stem 10,

this being given a longitudinal outward movement by the co-action of the threads 15 With the nut 5, and With the upward movement of the valve stem 10 the valve plate 13 is lifted from its seat 4 of the member 3, and thus allows the flow of liquid or fluid from the hydrant. 7

Having thus described our invention, What We claim and desire to secure by Letters Patent is:

1. In combination With a stand pipe, member secured to the upper end of said pipe and having an outwardly extending peripheral flange, a nut connectedto said member andarmnged on the interior ofthe pipe,

a head having a horiz'ont'al flange which turnably seats on the first named fian'ge,.a valve stemthreadedly engaged with the nut and having a valve thereon v'vhich seats on the first named flange, dependingguide elements connected to the flange of the head and extending over the periphery of the first named flange, and a pair of levers pivoted to two of said elements and having cams Which bear against the under .face 'o f the :fi'rst member secured to the upper endof said pipe'and having an outwardly extending peripheral flange, a nut connected to said memher andarrang'ed on the interior of the pipe, a head turnablyfseated on said flang'e, vguide elel'nents depending" from the head and ena e we: ri e irh y a an valve seating on the flange of 'saidmjember and having a stem engaged With "said head and threadedly engaged vvithv said nut, means connected to said elements to enable rotation of the head, meahs borne by said first named means for engagement with the under face of said flange to lock the head to the flange. g g

3; In combination Witha stand-pipe and a horizontal flange connected thereto and extending outwardly therefrom, a valve engageable with the flange, a head to which the valveis connected turnably seated on said things, and Vs'vvingable means borne by the head and engageablewith the under face. of

the flange to enable the head to be locked to the flange and also turned on the flange.

4. In combination With a standpipe and a member connected thereto and extending outwardly therefrom, said member being formed to have a valve seat on one side face thereof, a head turnably seated on the member, a valve connected to the head and engageable With said valve seat, and swingable means borne by the head and engaged Witlrsaidmember to lock the head against turning movement and to also enable turning of the head.

5. In combination with a stand-pipe and a member connected thereto and extending outwardly: therefrom, said member being formedto have a valve seat on one side face thereof, a valve engageable with said valve scana head connected to said valve andseated on said side face of the member in surrounding" relation to said valve, and means connected to said head and engageable Withthe opposite side face of the memher to lock the head against turning movef ment on said member.

6. In combination with a stand-pipe and a memberconnected thereto and extending outwardly therefrom a valve and a turn'able head connected to the valve which valv'e and head engage one side face of said member,

means connected to the head and engaged With the opposite side face of said member to lock the head against turning on said member.

7. lncoinbinati'on with a stand-pipe and a member connected thereto and extending outwardly therefrom, a valve and a turn'able head connected to the valve which valve and head engage one side face of said member, a stem on the valve, means borne by said member and arranged on the interior of the pipe to engage the valve stem Wherebyupon turning of the latter the valve Will be raised or lowered, and means connected to the head and enga ed With said member to lock the head against turning.

In testimony vvhereof We have hereunto set our hands in the presence of two subscribing Witnesses.
